Topic: Can I power the arduino with the power pins? (Read 3391 times) previous topic - next topic


My project at the minute powers the arduino's via the 5 volt pin. I know it's not totally wise but everything else is 5v i have a 5v regulated supply. I'm not putting a whole new supply in just for the Arduino's just so it can put it through a regulator and changed it to what i already have 5v. Having said that i have blown two uno's in the past when i connected the power in reverse. Some diodes i guess.


I have to agree with retrolefty here, how is this (electrically) any different from plugging the USB cable into the Arduino?
